Question

请帮帮我。我正在尝试使用do-while循环创建PowerShell脚本，如下所示：

询问用户文件夹名称（foldername）和目标IP地址（targetipaddress）
如果“foldername”不存在，则在“C：\”drive
使用“targetipaddress”作为目标路径的一部分，从网络驱动器路径的子文件夹“S：\”复制内容并粘贴到“C：\”路径中的“foldername”。
如果用户输入“quit”，则脚本完成。

我的代码如下：

$var = "welcome to IP address and folder creation world"
echo $var

# create foldername until user type "quit"
$output = (command)
do { 

$foldername = Read-Host "enter folder name "
$targetipaddress = Read-Host "enter target ip address "

# create folder name only if it does not exist
function createFolder {
$path = "\\$targetipaddress\C$\$foldername "
If (!(Test-Path $path))
{ 
      New-Item -ItemType Directory -Force $path
}

} # end of function createFolder

# copy contents from a sub folder of a network drive path and
# and paste them onto "C:\" drive path using "targetipaddress" and "foldername"

function copyContents {
 Copy-Item S:\sourcefolder\subfolder\*.*  \\$targetipaddress\C$\$foldername\ -Recurse
 }

 } while ($foldername = "quit") # end of do-while loop

请参阅下面的工作示例，仔细阅读并将其与您自己的相比较。

回波？它应该是写主持人
不必要和未使用的功能。
$ output =（command），它什么也没做。
同时，我喜欢使用while（$ true）并突破它。
可选，错误处理。
powershell不使用=（我相信你的意思是==）用于等级逻辑但是-eq

如果您在使用此代码时出错，请发送输入voor $ source，$ foldername，$ targetipaddress和$ path，我会查看它。

代码：

clear-host #clears your console, optional.
$ErrorActionPreference = "Stop" #prevents al lot of posible disasters from happening.

Write-Host "welcome to IP address and folder creation world" #Powershell way of writing to the console.

$source = "S:\sourcefolder\subfolder\*"
#$source = "C:\source\*" i used this for testing on my local machine.

# create foldername until user type "quit"
While ($true){ 

    "

    "#Add some white space between the questions.

    $foldername = Read-Host "enter folder name "
    If ($foldername -eq "quit") {break} #exit the while loop

    $targetipaddress = Read-Host "enter target ip address " #you could use a hostname to.

    $path = "\\$targetipaddress\C$\$foldername"

    #if connection to targetipaddress fails then abort.
    if(!(Test-Connection $targetipaddress -ErrorAction SilentlyContinue)) #look at the ! it means it should be false.
    {
        Write-Warning "Could not connect to '$targetipaddress'"
        continue #goes back to the begining of the while loop.
    }

    #if path does not exist try to create it.
    if(!(Test-Path $path)) #look at the ! it means it should be false.
    {
        try { New-Item -ItemType Directory -Path (Split-Path -Parent $path) -Name $foldername | Out-null } #Out-null prevenst unwanted console output.
        catch {
            Write-Warning "Could not create folder '$foldername' on '$targetipaddress'"
            continue #goes back to the begining of the while loop.
        }
    }

    #try to copy files.
    try { Copy-Item -Path $source -Destination $path -Recurse -Force }
    catch {
        Write-Warning "An Error occured while copying the files from '$source' to '$path'"
        continue #goes back to the begining of the while loop.
    }

    #if all goes well then tell them ;)
    Write-Host "files copied successfully from $source to $path"
